您可以将DrawMode
ListBox 的属性设置为DrawMode.OwnerDrawFixed
,这使您可以控制每个项目的整个图形表示.例如:
ListBox listBox = new ListBox();
listBox.DrawMode = DrawMode.OwnerDrawFixed;
listBox.DrawItem += new DrawItemEventHandler(listBox_DrawItem);
void listBox_DrawItem(object sender, DrawItemEventArgs e)
{
ListBox list = (ListBox)sender;
if (e.Index > -1)
{
object item = list.Items[e.Index];
e.DrawBackground();
e.DrawFocusRectangle();
Brush brush = new SolidBrush(e.ForeColor);
SizeF size = e.Graphics.MeasureString(item.ToString(), e.Font);
e.Graphics.DrawString(item.ToString(), e.Font, brush, e.Bounds.Left + (e.Bounds.Width / 2 - size.Width / 2), e.Bounds.Top + (e.Bounds.Height / 2 - size.Height / 2));
}
}
